      In the linked BF, we saw that if an exception was thrown inside of the storage_engine_impl constructor, we call into the KVEngine destructor which is a member of the storage_engine_impl instance. Then, when we call into the WiredTigerSessionDeleter here, we end up accessing the WiredTigerSessionCache after it has already been freed.
